Reached Legend in 19 Days Since Season Start

I played whenever I had time, casually climbing the ranks, and I finally reached Legend in 19 days (started from Master and it took about 380 games). I usually hit Legend near the end of each season, but this time I played a bit from the start, so I managed to reach it faster. (I wonder how few players there are if reaching Legend now still puts me around 1400th place...) I heard Ultimate opens this week, so I guess I'll have to grind that now. Here we go again with the grind...
